Twitter hasn’t had the best track record when it comes to diversity. Earlier this summer it was reported that there were only 49 Black workers at the company. Whites and Asians made up 93.8 percent of Twitter Inc., according findings.

Other tech companies at Silicon Valley have also come under scrutiny for their lack of female and minority employees.

In March, a former Twitter female employee sued the company claiming its promotion process unlawfully favored men.
